Definitions

  • the present invention relates to solenoid valves of the type comprising a mounting base comprising a first axial bore, an upper part comprising a second axial bore, supported on the base, concentrically thereto, by a tubular support part and held in position by a cover, a coil surrounding at least an axial part of the upper part, and a first and a second insert mounted respectively in the first and second axial bores and forming stops for the axially opposite ends forming valve means of a plunger structure resiliently stressed and comprising a passage of fluid passing through, at least the first insert comprising a passage of internal fluid opening into a valve seat closable by means of valve adjacent to the plunger structure.
  • a solenoid valve of this type is described in document FR-A-1 542 398.
  • the upper part constitutes the pole piece and is supported on the tubular support piece which forms the body of the solenoid valve and defines, above the base, an internal cavity for a complex frame structure supported and guided by flat springs flanged peripherally in the support part forming a body, in a delicate and expensive arrangement.
  • the object of the present invention is to propose improvements to solenoid valves of this type, of simplified design, which are robust, reliable, and precise while being suitable for mass production and allowing numerous adaptations retaining a large number of common parts of low manufacturing and assembly costs.
  • the base made of material with magnetic characteristics, comprises a part cylindrical inner pole piece projecting axially in the coil, towards the upper piece, and formed with a third coaxial bore, in the first and second bores, the plunger structure comprising a cylindrical core of magnetic material sliding in the first bore formed in the upper part and cooperating in engagement contact with a tubular extension part of non-magnetic material having an internal fluid passage and sliding in the third bore formed in the projecting inner part of the base.
  • the tubular support part is a tube made of non-magnetic material in which the opposite ends of the upper part and of the internal projecting part of the base which are typically sealed each are peripheral annular seal and a peripheral radial shoulder with which the corresponding end of the support tube cooperates in abutment, the assembly being locked in position by the cover consisting of a tubular piece of material with magnetic characteristics comprising a bottom bearing bearing against a external shoulder of the upper part and the free edge of which is crimped onto the mounting base, thereby looping the magnetic flux.
  • the solenoid valve comprises a mounting base, generally designated by the reference 1 comprising an external tubular projecting part 2 intended to be engaged in leaktight manner, by seals such as 3 , in a well 4 of a distribution block 5 comprising at least two fluid passages A and B opening at separate locations in the well 4.
  • the mounting base 1 comprises an intermediate flange part assembly 6 and a tubular projecting part 7 extending in the opposite direction to the external tubular projecting part 2, the mounting base 1 being made of magnetic material, for example pure iron.
  • the outer protruding part 2 is formed internally with a first bore 8 defining an internal chamber into which open, between the seals 3, radial openings 9 communicating with the fluid passage A.
  • the inner protruding part 7 is formed with a bore coaxial through 10 of smaller diameter opening into the first bore 8 and into the perfectly planar annular end face 11 of the inner projecting part 7, which is formed externally with an outwardly extending radial annular shoulder 12.
  • a support tube 13 made of non-magnetic material, for example stainless steel, cooperating at its lower end with the shoulder 12.
  • the inner end cylindrical of a tubular upper part 14 formed internally with a through axial bore 15 and, externally, with a first annular shoulder outwardly extending radial ular 16, intended to cooperate, in the final assembled configuration, with the upper end of the tube 13, and a second annular shoulder outwardly extending radial 17 intended to cooperate, as will be seen further on, with an assembly cover.
  • the space inside the tube 13 between the inner projecting part 7 of the base 1 and the upper part 14, is made watertight vis-à-vis the outside by annular seals 18 and 19 carried by the projecting part 7 and the upper part 14.
  • annular seals 18 and 19 carried by the projecting part 7 and the upper part 14.
  • Around the inner end of the upper part 14, of the tube 13 and of the inner projecting part 7 of the base 6 is arranged an electrical winding 20.
  • a tubular part 27 made of non-magnetic material, for example stainless steel or aluminum alloy, formed internally, over a part of its length, with a blind axial bore 28 of axial extension greater than the axial extension of the bore 10 and communicating with the outside, in the vicinity of its bottom part, by radial slots 29.
  • the end of the tubular part 27 opposite the opening opening of the bore 28 and extending into the bore 8 carries a valve means 30, typically constituted by a ball set in the end of the part tubular 27.
  • the core 31 are formed at least one, typically at least two axial channels 33 opening, at the upper part of the core 31, on either side of the valve means 32 and, advantageously communicating, at the lower part of the core 31 , with an internal end chamber 34 facing the through end of the blind bore 28 of the tubular part 27.
  • a tubular insert 36 comprising an external thread cooperating with a thread formed in the upper end of the bore 15, the insert 36 having an end slot 37 allowing it to be screwed into the bore 15.
  • the insert 36 has an axial through passage 38 opening into the lower end of the insert 36 by forming a valve seat 39 intended to cooperate with the adjacent valve means 32 formed at the upper end of the core 31.
  • an insert 41 comprising an external thread cooperating with a thread formed in the lower end of the bore 8 and provided with a slot 42 allowing its screwing.
  • the insert 41 is formed with an axial through passage 43 opening into its upper end face by forming a valve seat 44 intended to cooperate with the valve means 30 formed in the end of the tubular part 27.
  • a biasing spring 45 is mounted between the inner end face of the insert 41 and a peripheral shoulder of the tubular part 27 so as to bias the latter in abutment against the underside of the core 31 and, consequently, the latter pressing, via its valve means 32, against the seat 39 in the inner end face of the upper insert 36.
  • the lower insert 41 ⁇ comprises, here, a transverse fluid passage portion 46 establishing communication between the central axial passage 43 opening into the valve seat 44 and a peripheral annular groove 47 communicating with the radial openings 9, as well as '' a second axial through passage 48 opening directly into the internal chamber formed by the bore 8 of the base 1, parallel to the first central axial passage 43, which typically comprises, in an enlarged end part, a labyrinth structure 49
  • the lower insert 41 ⁇ comprises at least one orifice 50 for a tool allowing it to be screwed into the bore 8.
  • the solenoid valves according to the present invention find, due to their small size, their robustness, and their short response time, various applications, in particular in high pressure installations, for example in anti-lock braking circuits.
  • the solenoid valve arrangement according to FIG. 1 will be used as an isolation and expansion solenoid valve, the entry of pressurized fluid taking place through passage B towards the valve seat 44, passage A being connected to the operating circuit and passage C, communicating with the valve seat 39, being connected to a low pressure tank, the solenoid valve arrangement according to FIG.
